The fact that you don’t get your period after five days of bleeding doesn’t necessarily mean that you’re pregnant. After intercourse, fertilization will be completed within 24 hours of ovulation. 6-7 days after fertilization, the fertilized egg will move into the uterine cavity and complete implantation, so the implantation of the fertilized egg occurs on the 21st and 22nd days of the menstrual cycle, and some women may experience a small amount of vaginal bleeding during the implantation period, and 5 days after implantation on the 26th and 27th days of menstruation, and the absence of a period does not necessarily mean that you’re pregnant. For pregnant women, blood HCG (human chorionic gonadotropin) test can be performed around 10-14 days after intercourse to confirm pregnancy. When the result is positive, ultrasound examination should be performed at around 6 weeks after menopause to confirm normal pregnancy as prescribed by the doctor. If the result is negative, the pregnancy can be monitored for the time being, and the patient should be retested as prescribed by the doctor.
